Application filed October 1, 1925 seria1 Norma.

My invention relates to novel means for facilitating the proper production and quick and accurate positioning of the cutting blades or knives for the heads of planingor moulding machines and concerns more par lticulafrly, but-not restrictedly, structures or gauges of this general type adapted for satisfactory employment in woodworking machinesequipped with round heads and using thinknives of high-speed steel which canbe ground and fittedforthe work without affecting their temper and'whichnaturally hold'their sharp cutting edges longer, as distinguished from square-heads employ ingrelatively-thick, milled-to-p attern cutters. 7

.Such thin knives can be easily canted or tilted in'the head to secure their correct locations, the use of knives of this'style avoid ing a large amount of grinding and rendering possible a single knife for a plurality of different patterns or designs, hence eflecting a substantial saving in cost. 1 I

The improved gauge may be satisfactorily used for positioning straighter pattern or moulding knives or both.

To permit those'skilled in this art to understand" the structural and functio'naladgvantages accruing from the use of appliances incorporating the Valuable features of this invention, in the accompanying drawings, forming a part of this specification, and to which reference should be had in connection. with the following detailed description, and

throughout the several views of whichlike designatethe same elements, a presentdesirable and preferred embodiment of the invention has been depicted, but, of course, it I v I I ;gether than'showln, or may be formed as a v,

is to be understood that'the invention is susceptible of a variety of embodiments differing from one another more or less radically in vstructural details, but all incorporating the'funda mental principles involved,'as delined by he constructions presented 'in the appended claims. v I In these drawings: Figure ,Ifshows a plied, the latter being illustratedfin section; Figure 2 is a planview of the structure presented in Figure 1;

' 'For'; setting :oradjustihg a plurality of straight-edge knives in the head without 7 movmg the gauge, which is sometimes ide sirable, a structure such as is shown, in Figures l and 2 is employed.

The round head ll hasany appropriate or in suitable number of-slots 12 for the accommodation of a jcorresponding number of thin knives or blades13, and 14: with straight cutting edges, non-skid gibs, 15 and associated holding means16 and their'adjustmentor 17' of vvknown commercial 19 extended through an aperture 21 in the gauge and'takinginto a threaded hole 22 in the head provided for that purpose,

To afford clearance between thegauge and head, so that foreign matter. adhering. to

either p art will not interfere with the proper performance of the required functions,,the gauge has a number,1n thepresent lnstance four, set-screws, 23 extended therethrough {with their "ends, in contact withithe cylindrical surface of the head, whereby the two members are 1 maintained spaced; apart, a slight ,distanceizR V a At one'end, the gaugehasa pair of spaced,

' facture of moulding, n most cases,

By this simple means the several straightedge knives or cutting blades of the head or cylinder may be quickly and accurately located and fastened or secured in place, the

overlappingthe end of the dovetail groove to act as an abutment or limiting member against which the corresponding end of the element 27 is designed to bear.

Also, the gauge 18 conveniently has a stopscrew 31 at one end overlapping the end of the head to assist in the correct and exact application of the demountable gauge to such member 11.

Inthe setting up of a head for the manuthere is a straight out which,in the terminology of the trade, is known bythe moulder operators as the base line cut.

In Figures 3 and 4 of the drawings the newgauge is so arranged that it will facilitate the positive'and accurate positioning of the straight-edge knife which "makes such 7 base line out, givinga definite line with relation'to which the mouldingcutters may be set up, and both types or styles of knives maybe correctly located with reference to "one another without moving the attachment which the desired result is accomplished;

In this instance, the parts are as already described, except that the dovetail groove 26 ire-celves a layout and adjustment scale 32 for cooperating with the correlated moulden, knife 33, the part 32 being made of any suitable material for ready and easy insertion in the groove on the face ofthe gauge and on which a pencilmark can be readily made and retained, the scale, as shown in Figure 4, having equally and closely spaced, horizontal' and vertical, or longitudinal and transverse scale lines. I

Ittis a relatively simple matter t0 lay on i I a moulding' cutter lofany particular pattern 1th exact tudeand precision on this scale,'

1 and, after the design has been completed and the "cutterground' thereto, the scale is slipped or slid into the gauge groove, assuming that the gauge has been apphed to the head, and the cutter is thenset ,to the lay-out on the scale and firmly secured in place with correct relation to the associated straight-edge knife, the position of which is determined by the other end of the gauge.

The advantage of applying the design or shape" of the cutter on the scale resides not only in the production of and in the setting of the knifein the head, but the scale can be filed away as a record when the run has been completed, and when: it is required again, it can bereplaced in the gauge andfthe set upcan be quickly and correctly made as before, or, if the cutter becomes broken or lost, the operator has merelyto grind a new one to fit the pattern en the scale and position it by the latter 1n the head. I o q If desired, the manufacturer of the moulder may supply suitable scales with the designs already thereon for any type of moulding or may furnish ground cutters for use with previouslyprepared scales.

In case it is desired to use more than two cutters for moulding, or, in other words, if

one wishes to employ four moulding cutters in a four-knife round head, in applying and adjusting them in the head advantage is taken of the space between the gauge lugs 24, 24, for the accommodation of a-knife al ready set while the next one is undergoing adjustment.

Thoseacquainted with the requirements of this artwill understand that the invention, as defined by the appended claims, is not limited or restricted to the precise and exact details of structure'presented and that many minor mechanical changes may be incorporated therein without exceeding the purview a of the invention and without the loss or sacri- I lice of any of its material benefits and advantages.
